Feedline Attachment And Grounding; Ground Rod Installation - Hy-Gain AV-18HT Instruction Manual

Feedline Attachment and Grounding

Install two ground rods at each tower leg.
Space them 24" from the leg with 18" between
the two rods as shown in Figure 15. Use 1/2" x
8' copper clad steel rods (not supplied) for a
good ground.
Attach each rod to a pip leg..using #10 or
larger copper wire (not supplied). Now connect
the three pipe legs together as shown in Figure
15.
Strip your coaxial cable and attach the center
conductor to the tower base using the hole
provided as shown in Figure 15. Attach the
braid to a pipe leg. Cover the exposed coax
cable dielectric to prevent U.V. cracking.
Weatherproof the coaxial cable using Coax-
Seal© or some similar substance to prevent
water from entering and ruining the coax.
The overall efficiency of the 18-HT -S can be
improved by adding a radial system. The next
section describes how to install a radial
system.
